single vs dual service providers

Companies don’t always have high availability. What’s more, there is always a concern of budget and complexity with the high availability even though a number of factors need to be considered during network design.

If the applications of the company do not require high availability, dual carrier or two links to the same carrier is not necessary.

Multihoming refers to a connection to the two different carriers/service providers even though two routers via two links to the same provider is not considered multihomed.
